i This invention -relates nto vending machines and more particularly tofsuch machines of the coin-controlled i typer`r adapted to v4dispensing of packaged goods, i such as .-bottled.. beverages, canned goods and the like.

One of the objects of-my present invention is to provide a coin-controlled vending machine wherein a quantity of articlesfto be dispensed is compactly carried inA a .pluralityof adjacent columns within an enclosure for sequential and automatic vendingatherefrom,l one at atime, under the 'control of a mechanismhaving provisions for insuring thedeliveryvof an article or the returnof thefcoin.

Another object of theinvention is to provide a coin-controlled vending machine havingadjacent sections withinan enclosure for ysupporting columns of articles to be dispensed, each of which sections `and its .f accompanyingk lvending .mechanism is'adapted -to handle articles of various sizes and shapes, within reasonable limits of variation.

Y For arfurther object, my invention comprehends the provision o a vendingmachine wherein the articles to be dispensed lare disposed incolumns .and each columncomprises a plurality of adjacent rows, from. which rows the articles are fed to delivery. positions by gravityand sequentiallydelivered under` the control of a positively actuatedl delivery control mechanism.

It isanother objectvof, this ,invention to provide a vending machine .including acontrolele" ment adapted to actuation directly by the articles contained in and dispensed by the machine'for eiecting an Iindication when thev machine is.-

empty and normally for insuring the,v delivery of an articlek each time the machine is operated.

My invention also has` for an lobject the provision'of a vending machine having one or more of the features referred to and incorporating f parts constructed and arranged to prevent piliering` of the 4articles therefrom.

Other objects and advantages of the invention will be apparent fromthe following description and the accompanying drawings in which similar characters of reference indicate similar parts throughout the several views.

ln the exemplary embodiment of myinvention which is shown inthe accompanying drawings, I have illustrated4 its adaptation tothe vending of bottled beverages. l For the vending of any particular kinder size of article whichis suited to the use of, themechanism, the sizes of theparts and the type of enclosure are suited to the article. In the presentv instancathe bottled beverages are to be cooled before being'dispensed. Hence, an outer enclosure lil, as indicated in Figs; 1, 2 and 3, comprises a cabinet .having af-ront'wall I2,

side Walls i3, back wall 14, and a top Wall l5, all

of which walls are made up of an outer covering of sheet metal IB filled with `heat-insulatingV material Il. In the present adaptation a relatively small opening I8 is providedat thefront of the outer enclosure through which articles are dispensed. Above the opening -l8the front wall I2 of the outer enclosure desirably includes a'panel I9 whichis removable to provide access to the interior of the enclosure .and which may be locked in position relative to ythe enclosure so as to be removable only by..an. authorized person.

Within the upper portionofthe outer enclosure a rack, which is indicated generally by the reference numeral 2ll,.carries Athearticles which are to be dispensed andsupports the major portion of the vending mechanism. A chute 22 has a rear portion which'underlies the rack 20 and slopes downwardly toward the inner end of the opening It to guideH articles `dispensed `from the rackvto anl adjoining chuteextension .23 which extends through the'ropening` I8 and has an end flange 24 thereon which isdesirably ylined. with resilientmaterial;` such asa strip of rubber 25, for stopping .the varticles as they. are dispensed. This general arrangementof theparts leaves the lower portion rof the outer enclosure for housing a suitable refrigeratingmechanism (not shown).

' being secured tovan upper cross bar 42.

is mounted Within the upper rear portion of the outer enclosure for circulating the cooled air from the refrigerator unit across the retained articles. Ey preference, a balile plate 21 (Fig. 2) extends over the fan in the upper rear corner of the enclosure to improve the circulation of the chilled air. In order to prevent undue heat loss through the opening I8, a door 28 of heat insulating materialis supported for swinging movement by a hinge 29 at the top thereof so that it is swung outwardly by the movement of a dispensed article along the chute 22 and chute extension 23, and normally gravitates to its closed position whenV there is no obstruction, such as a dispensed artrcle, to prevent its closing movement.

The rack 23 includes a substantially U-shaped base frame 38 having a relatively straight and rigid iront portion 32 and relatively straight and opposed side portions 33 which are desirably formed integrally with the front portion and extend rearwardly in substantially parallel relationship. Angle strips 3d are secured to opposite Outer surfaces of the base frame side portions 33 and are carried by angle strips 35 which are secured to opposite interior surfaces of the sidewalls i 3 of the outer enclosure to support the rack. The rear ends of the base frame side por tions 33 are secured to and connected by a sheet metal back plate 35 which provides a rear wall for the rack and has an opening 31 therein adjacent the fan 26 for the circulation of cooling air to the articles carried by the rack.

A plurality of substantially U-shaped' bars 38 have straight intermediate portions 39 extending vertically along the inner surface of the back plate 3S and substantially parallel end portions Ml extending forwardly therefrom; the forward ends of the lower end portions being secured to the inner surface of the base frame front portion 32. and the forwardends of the upper end portions Bars li'l have their opposite ends secured to and extend upwardly between the front base fram'e portion 32 and the upper cross bar l2 in positions opposite` Vthe straight intermediate portions of the Ur .shaped bars 33. Laterally the U-shaped bars 38' are disposed in equally spaced relationship relative to one another and the outer ones of the bars are displaced from the base frame side portion, are disposed in spaced rows with their lower ends secured to the base frame side portions 33 Y and the Support bars 43, and their upper ends secured to similar suitable frame members. The

guide Vtubes 44 laterally define a plurality of sim--` Q6 which are to be dispensed are carried'therebetween in laterally spaced vertical rows, as

shown in Figs. 3 and 6. As shown in Fig. 5, filler pieces 41 may be interchangeably connected to the surfaces of the guide tubes 44 to provide varations inthe section widths to accommodate differentsizes `of articles in a single machine.

As shown in Figs. 1y and 3, the complete vend ing machine, in the present instance, includes four sections in side-by-side relationship, each of which sections holds two laterally displaced and vertically disposed rows of articles to be vended.

so as to separate the articles of adjacent rows from one another, I have provided each section with a series of vertically separated spacer bails 48 and a' retaining bail 49, each of which bails has aligned endportions 50 and 52 (Fig. 2) and a substantially straight mid-portion53 which is offset from the aligned end portion. The spacer bails 48 and the retaining bail 49 have their aligned end portions' rotatably supported in aligned openings 54 in the bars 4I and the straight intermediate portions 39'of the U-shaped bars 38 so that the bails extend longitudinally of the sections from end to end and are normally midway between the guide tubes 44. vThus the bails are supported for swinging movement laterally of the sections.

By preference, each of the bails, except the lowermost two, has a roller 55 of resilient material, such as rubber, rotatably mounted on the straight mid-portion thereof, each of which roll-Y ers serves the dual'purpose of providing a cushioning surface for engagement with the `articles and a rolling surface to facilitate the passage of articles downwardly'through eachsection. Although such rollers of resilient material would Vnormally be quite desirable and effective on the lowermost two of the bails, those two have been excepted in the present instance in order to pro- Y Vstood that the cutting away'or removal of one of the exposed rollers might well provide sufficient space for articles to pass from the sections at one yor both sides of the bails.

In the normal operation of my vending machine, the articles to be dispensed are put into the sections fromY the top and placed alternately on opposite sides of the bails in each section. The retaining bail at the lower end of each section `controls the release of the articles from that -section and has its position determined so that it is angularly disposed to one side or the other of the .bar 4| to retain the lowermost article in the section on the slderthereof toward which its mid-portion extends. As depicted in Fig. 6, the determination by the retaining bail of the row in which the lowermost article of each section is retained also determines the positions of the remaining articles in that section and the bails carrying rollers4 which intervene between the remaining articles. The rollers above that on the retaining bail are each interposed between adjacent articles of the two rows; those rollers and the accompanying bails being biased to that position bythe weight of the supported articles. Each time the retaining bail isshifted from a position supporting the lowermost article -cams A58, '59,v Sil and 62.- bodiment of my l invention; the dispensing of articles from vtwosections on one side/oi the in one row to a position of support for the lower- AIn order to Aprovide definite control and positive actuationy for determining` the positions of the retaining hails 59 for each of the' sections,

I-Ience .the cams 53* and 59 Yare secured to a shaft 63 which is rotatably supported by :bearingsV 64 and 65 and drivingly connected at one end to a motor "55,V cams 60 and 62 are-secured to-a shaft G57V which is rotatably supported by the bearing 65 andfa -bearin gii8and drivingly connected at onev end to a motor 69, The bearings 64, 65 and 68 have integral flanges 10, 'I2 and 13, respectively, which are integrally formed thereon and secured to the front surface ofthe base frame 3G so that the shaftsy 63 and'tl'ex,

tend laterally across 'the lower front portion of the rack in end-to-end relationshipfthe bearing 65 providinga common support for theY ends of the two shafts. Brackets T4 and-5 on the "housings of the nrotors' and69, respectivelm. lare also secured to the base 'fraxneSU to support those motors in positions 'for driving'conm -nections withfouteropposite ends of thef'two shafts. y

As depicted in Figs. 1, 3 and 6, the cams Gil and 62 have cam tracks in theforrnY of Vc'shannels 'i6 and 11, respectively, dened by separated and opposed flanges y'I8 on 'the-cani lil andsifrnilar 4spaced and opposed flanges 'i9' on the can'r62. The channelr 'Hi of the camfll has actuating portions 80 in diametricaliy opposed positions and dwell portions 82 in vdiametrically opposed positions. Likewise, the channel 11 of the cam 62V has actuating portions 83 in diametrically opposed vpositions and vdwell portions: 847in diametrically `opposed positions. fThe projecting tips ofthe crank-like end portions 57 on theretaining bails V49 ride in the channels 'Hi and 'H of the cams 60 and B2, respectively, and have their positions determined thereby. v

In order to provide relatively quick actuation of the retaining bails from one article-retaining position to the other and so as to provide longer periods during which the retainingY bails are held `in one or the other of their retaining 'positions, the dwell portions of vthe channels" are relatively long and. cover a substantial portion of each half of' a camrevolution, while the`ac tuating portions of the channels'are relatively short cir'curnferentialiy of the cam'anid are disposed in relatively sharpangular relationship to the dwell portions. The'axial lengthoftheactuating portions of the channels is sufficient to effect the movement of each" of the retaining bails from a position underlying one row"of"articles to a position underlying the adjacentl row of 4articles in 4rthat section.` The cams' 58 'and'59 are respectively similar in construction and operation to the cams 62 and 60, respectively,

and similar portions are referred to by like 'reference numerals;

When the coin rejector' winding is thus energized, normal operation of the coin slide occurs upon the deposit of a coin. However, when the coin reject-or winding 89 is deenergized, as it is during the operation of the motor 69, or when the circuit thereto through the switch 99 is broken, or even in the instance of a power failure, vthe coin is returned to the deposit-or through a suitable coin return chute.

When both of the 'sections controlled by thel motor B9 are empty, the switch 99 not only breaks the circuit to the coin rejector winding so that the coin will be returned, but it `also closes a circuit through contact |02 to a signal light |03. The signal lightprovides an indication'that the portion of the machine whichV Vis controlled through the coin slide 86 is empty.

By reference to Fig. 2 is may be observed that the switches 95 and 99, which have been referred to in connection with the circuit diagram disclosed in Fig. 7, are mounted in spaced relationship yon brackets |04 and |05, respectively, and in spaced relationship at the rear of the rack. A vane |06 is supported for'rotary movement on a shaft |01 which extends laterally of the sections and is spaced somewhat below the lower ends of the sections. This vane has forwardly projecting arms |08 which underlie each of the sections controlled by one of the motors. On the opposite side of the shaft |01 from the arms |08 each vane has a rearwardly projecting portion I 09 which carries a weight |I0, which weight normally biases the arms |08 towardk the sections which they underlie and issuiiiciently heavy to effect operation of the switch 99'when the actuating element I2 of that switch is engaged by the lower surface of the rearwardlyprojecting portion |09 of the vane.

which is under the control of an element responsive to the release of an article from one of the sections for effecting stoppage of the prime In the operation of the mechanism, each of the vanes |06 is biased by its weight I0 to a position, such as that indicated in solid lines in Fig. 2, in which position at least one of the arms |08 is in engagement with the lowermcst article in one of the sections and both of the switches 95 and 99 are in their normal positions which arev indicated in Fig. 7. If both sections which are controlled by the motor 69 are empty so that there is no bottle for any one ofV the arms |08 Yto engage, the arms move to an abnormal angular position, such as that indicated in dot and dash lines at |03a, and the rearwardlyl projecting por-'- tion moves downwardly to a position, such as that indicated by d-ot and dash lines at I09a, to eiTeCt operation of the switch 99, as described, to open Y the circuit to the coin rejectcr winding 88 and.

close the circuit to the signal light |03.

When there are articles in the section and one Y of them is released upon the deposit vof a coin so that it drops through a position such as that .indicated at 40a and then falls to the slide, the 'weight of that released article overcomes the biasing force of the weight ||0 and moves the arm of the vane downwardly to a position such as that indicated at |0812, whereupon the rearwardly projecting portion of the vane movesA upwardly, as indicated at |0917, to a position suchthat the weight H0 engages theV switch 95 and thereby opens the circuit to the motor to: stop the dispensing mechanism. l 1

From the foregoing description it maybe understood that 'through' the sequential operation of a plurality of sections by a single prime mover mover, -a factor of insurance is provided that an article will be delivered-upon each deposit of a coin when the machine is not empty. That is, if one section is empty or if for some abnormal reason an article fails to be released upon the Y operation of one of the retaining bails, theY prime precise details of construction set forth, but desire toy avail myself of all changes within the scope of the appended claims. Y
